EK60 Water Column Sonar Data Collected During GU1202

Deploy satellite telemetry tags on suitable specimens of sperm whale and Bryde’s whale. 2. Collect tissue biopsy samples, detailed photographs, detailed video, fecal samples and close-range acoustic recordings of select marine animal species. 3. Collect visual and passive acoustic data to characterize sperm whale abundance and spatial distribution in the Southeastern Gulf. 4. Collect tissue samples (biopsies) of select cetaceans from the bow of Gordon Gunter. 5. Collect acoustic recordings of marine mammal vocalizations for use in species identification. 6. Collect oceanographic and environmental data including hydrographic profiles (CTD and XBT), continuous surface water characteristics (SSCS), and scientific echosounders (EK60) data to quantify acoustic backscatter due to small fish and zooplankton.
